When the egg carriage 3 is positioned in the solid line position, as shown in Fig. 1 of the drawings, the egg turning roller 2li is arranged to rotate the egg retained by the egg retaining rollers 3f, as indicated by dash lines in Fig. 1 of the drawings. This egg turning roller 24 is provided with soft resilient roller portions 24a, at its opposite end, which portions 2da. are preferably of soft rubber or the like and this egg turning roller 24 is revolubly mounted intermediate the extending ends of the egg turning roller supporting bracket 29, as shown best in Figs. 1 and 5 of the drawings. This egg turning roller 24 is provided with a central shaft 2M) on which is rigidly positioned the egg turning roller operating gear 25 which is positioned intermediate the egg engaging roller portions 25a, as shown best in Fig. 5 of the drawings.

In meshed relation with this gear 25 is the gear 26, which is revolubly mounted in a similar manner in connection with the bracket 29, as is the egg turning roller 2li. Revolubly mounted in connection with the bracket 29 in meshed relation with the gear 25 is the egg turning roller operating gear 2l. This gear 2l is arranged in xed revoluble relation with the egg turning roller operating pulley 3l engaging the egg turning roller operating belt 3d. This belt Sli is positioned over the pulley 33 on the shaft 20 and is positioned over the pulley 32 intermediate the pulleys 3| and 33, all as shown best in Fig. 1 of the drawings. in connection with the main frame I by means of the bracket 32a.

The egg turning roller supporting bracket 23 is a substantially U-shaped bracket member supported on the upper side of the frame portions ia by means of a cross member 28a, which is' arranged in interconnected relation with opposite side portions of the horizontally disposed portions Ia of the main iragme I, as shown best in 2 of the drawings. This bracket 28 is pivotally mounted at its middle portion on a bolt 23h which extends through the cross member 2Enl, all as shown best in Fig. 2 of the drawings. This pivotally mounted relation of the bracket 23 in connection with the' main frame portions la provides a shifting relation of the egg turning roller 2li with the egg carriage 3 providing a means arranged to compensate for various contours of eggs in the egg carriage 3 and also for reverse longitudinally disposed relation of eggs in said egg carriage 3 and in adjacent operative relation with said egg turning rollers 2'3, all as shown best in Figs. 1 and 2 The bracket operating springs 35 in connection with the brackets 28 and 29 tend to force the bracket 2S downwardly toward the egg carriage 3 for frictional engagement of the egg turning roller 2li with the eggs in the egg carriage 3, all as shown best in Fig. 1 of the drawings.

It will be noted that the bracket 29 is provided with a stop member 29a arranged to engage the upper end of the bracket 2B limiting the downward movement of the egg turning roller Eri in connection with said bracket 29.

The pulley 33 is fixed on this shaft 20 and is arranged to operate the egg turning roller 24 by means of the belt 34 and the gears 25, 26 and 21, as hereinbefore described. It will be here noted that the egg turning roller 24 operates at fairly high speed due to the geared` relation of the small gear 25 relatively with the larger gear 26 in mesh with a still larger gear 21.

.The shaft I9 isjournalled in the journal brackets lila, I9b, I9c and I9d, as shown best in Fig. 1 of the drawings. It will be here noted that the brackets I9a, |911, I9c and I9d are each rigidly connected with the main frame I.

The brush supporting bracket 42 is a substantially U-shaped bracket member pivotally mounted in connection with the main frame I on the bolt 42a. as shown best in Fig. 1 of the drawings.

Pivotally connected with this brush supporting bracket 42 by means of the pin 42h is the brush supporting bracket 43, as shown best in Figs. 1 and '7 of the drawings. The brush supporting bracket 43 is provided with bifurcated portions arranged in upwardly extending relation and substantially T-shaped in form as shown best in Figs. 1 and 7 of the drawings.

Secured on this brush supporting bracket 43 at one side thereof by means of the angular bracket 44a is the brush operating motor 44. Secured on the operating shaft of this brush operating motor 44 is the brush operating gear 40 which is a relatively small gear acting as a pinion intermediate the larger brush operating gears 39 and 4I which are in meshed relation with said brush operating gear 40 and are arranged to revolve the brush supporting shaft members 31a and 38a, as shown best in Fig. 5 of the drawings.

It will be noted that the gears y39 and 4I are in rigid connected relation with the brush supporting shaft 38a and 31a respectively, which shafts 31a and 38a are revolubly mounted in the bifurcated portion of the brush supporting bracket 43 whereby said gears 39 :and 4I are interposed between said bifurcated portions of the brush supporting bracket 43, all as shown best in Fig. of the drawings.

Rigidly connected with the extended ends of the shafts 31a and 38a are the brushes 31 and 38, as shown best in Figs. 1 and 7 of the vdrawings. These brushes 31 and 38 are arranged to be positioned in tandem relation slightly above the egg carriage 3, as shown in the solid line position in Fig. 1 and near the egg turning roller 24. These brushes 31 and 38 are soft and are preferably made of fine resilient wire bristles arranged around the middle of each ofv said brushes 31 and 38.

The brush shifting lever 45 is pivotally mounted on a pin 45a which is rigidly secured to the main frame I, as shown best in Figs. 5 and 7 of the drawings. This brush shifting lever 45 is provided with a guide bracket 45h, as shown best in Figs. 1, 5 and 7 of the drawings. This brush shifting lever 45 is arranged to be engaged on its under side edge by the cam member 36 which is revolubly operated by the shaft I 9.

The link member 41 is arranged to interconnect the extending end of the brush shifting lever 45 and the extending arm portion 43a of the brush supporting bracket 43, as shown best in Fig. 7 of the drawings. The brush shifting lever 46 is pivotally mounted on a pin 46a. and is provided with an upwardly extending end in substantially radiating -positionY portion 46h with which is connected the link member 48. The opposite end of this link member 48 is connected with an outwardly extending'bracket portion 42e of the brush supporting bracket 42, as shown best in Figs. 1 and '1 of the drawings. The brush shifting lever 46 is provided with an angularly extending end portion 46c which is arranged to engage the cam member 35, as shown best in Fig. 7 of the drawings. As indicated by dash lines in Fig. '7 of the drawings, the cam members 35 and 36 are arranged to shift the brush shifting levers 45 and 45 respectively. It will be here noted that opposite ends of each of the link members 41 and 48 are provided with ball and socket connection means, as shown best in detail in Figs. 3 and 4 of the drawings. As shown in Fig. 4 of the drawings, the brush shifting lever 45 near its one end is arranged to receive the bolt shank portion 41a of the ball joint member 41h. This ball joint member 41h is positioned in :a ball socket member 41C which is rigidly connected to the main shank portion of the link member 41, as shown best in Fig. 3 of the drawings. Screwthreaded in one end of this socket member 41c is a plug 41d which is arranged to retain the ball joint member 41e in substantially the position as shown in Fig. 3 of the drawings. This ball and socket joint means at opposite ends of each of the link members 41 :and 48 provide for angular shifting relation of the. link members 41 and 46 with the brush shifting levers 45 and 46 respectively and the brackets 43 and 42 respectively.

Interconnecting the extending arm portion 43a of the brush supporting bracket 43 and the bolt 42a of the brush supporting bracket 42 is a tension spring 43h, which tends to force the brush supporting bracket 43 toward the end portion 46h of the brush shifting lever 46, as shown in Fig. 7 of the drawings. As shown in Fig. 5 of the drawings, the dash line position of the brush operating shaft 31a. and 38a illustrate the position taken by the brush supporting brackets 42 and 43 when the brush shifting lever 46 operated by the cam member 35 pivots the brush supporting bracket 42 on the bolt 42a.

The operation of my egg cleaning machine is substantially as follows: The egg feed rack 2 is loaded with eggs as indicated by dash line A in Fig. 1 of the drawings. The revoluble operation of the shaft 25 is started by means of a motor in connection with the main drive pulley 23, which motor is not shown. As the shaft 20 turns, the pulley 33 engaging the belt 34 revolve the pulley 3I operating the gears25, 26 and 21 together with the egg turning roller 24 providing relatively high speed revoluble operation of said egg turning roller 24. The brush operating motor 44 in connection with the brush operating gears 39, 40 and 4I revolves the brushes 31 and 38. The worm pinion 22 on the shaft 20 in meshed relation with the worm gear 2I revolves the shaft I9, together with the cam members I8, 35 and 36. When the egg carriage 3 is positioned in the solid line position of Fig. 1, the brushes 31 and 38 impart rotary brushing action on the outer surface of the egg in said egg carriage 3. It will be observed in reference to Fig. 7 of the drawings, that the brush shifting lever 45 operatedby the cam member 36, shifts the brush supporting bracket 43 by means of the link member 41 into various dash line positions from one end to the other of the egg in the egg carriage 3. The shifting of said brushes over the outer curved contours of the egg is accomplished by the pivoted relation of the brush supporting bracket 43 on the pin 421), as shown best in Fig. '1 of the drawings. While the brushes 31 and 38 are brushing and cleaning the outer surface of vthe egg, said egg is revolved in the egg carriage 3 by means of the egg turning roller 24 in engagement with said egg. 'Ihe rollers 3f of the egg carriage 3 provide relatively free and easy revoluble operation of said egg in the egg carriage 3. After the egg has been thoroughly cleaned, the brush supporting brackets 42 and 43 are pivotally shifted on the bolt 42a to the dash line position, as shown in Fig. 5 of the drawings by means of the tension spring 43h acting against the cam member 38 in its downward revoluble movement beneath the brush shifting lever 45. The egg carriage 3 is then shifted on the egg carriage track member 4 toward the egg feed rack 2 by means of the cam member I8 which engages the upper side of the carriage shifting lever l1 and forces the same downwardly to the dash line position, as shown in Fig. 8 of the drawings. When the carriage shifting lever l1 is forced downwardly to the dash line position. as indicated in Fig. 8 of the drawings, the carriage 3 is positioned in substantially the dash line position adjacent the lower end of the egg feed rack 2, as shown in Fig. 1 of the drawings. 'When the egg carriage 3 is thus positioned it is in engagement with the egg retaining lever i6 and holding the same beneath the upper side of the egg feed rack 2 permitting an egg to pass downwardly into the egg carriage 3 intermediate the rollers 3f thereof. The cam member I8 then releases the carriage shifting lever I1 gradually and permits the resilient cable Il to shift the egg carriage backwardly toward the brushes 31 and 38 by means of the cable 5. It will be here noted that as the egg carriage 3 passes toward the egg feed rack 2 from the brushes 31 and 38 carrying a clean egg therein, the ejector trip lever i4 engages the trip lever cam member l5, as hereinbefore described, shifting the egg ejector member I2 and i3 into the dash line position, as shown in Fig. 9 of the drawings, ejecting the cleaned egg from the egg carriage 3 over the one side of the egg carriage 3 and into a conveyor, which is not shown and is no part of my present invention. It will be here noted that as the egg carriage 3 receives an egg from the egg feed rack 2 and proceeds backwardly toward the brushes 31 and 33, the egg retaining lever i6 passes upwardly intermediate the egg carried by the egg carriage 3 and the adjacent oncoming egg passing downwardly on the upper side of the egg feed rack 2. This egg retaining lever l5 holds the eggs on the egg feed rack 2 and prevents them from passing downwardly over the lower end thereof when the egg carriage 3 is not in proper position to receive one of said eggs from the egg feed rack 2, as indicated by solid lines in Fig. 1 of the drawings. It will be readily understood that my egg cleaning machine is substantially automatic. The only manual act required in the operation thereof is placing the eggs on the egg feed rack 2, the eggs thereafter. being handled entirely by my egg cleaning machine and ejected therefrom.
